Assigning to NetworkManager component; apologies if this is not the correct component. As the reporter says in the description he disables NetworkManager, then this can't be a NetworkManager problem. But rather it is dealt by legacy initscripts. However, I doubt there is a problem and the report should be probably closed. PEERDNS is described in /usr/share/doc/initscripts/sysconfig.txt. And it is also mentioned in man nm-settings-ifcfg-rh, stating that there is a slight difference in behaviour when using NetworkManager. For not touching resolv.conf during NetworkManager operation there is a configuration option dns=none (man NetworkManager.conf). There are also useful links in comment #3 and comment #4. Can you attach you configuration? I actually seem to be seeing this problem on F23 (but was not on F21). With F23 and this /etc/sysconfig/network-scripts/ifcfg-eth0: DEVICE="eth0" HWADDR="XX:XX:XX:XX:XX:XX" BOOTPROTO="dhcp" ONBOOT="yes" PEERDNS="no" IPV6INIT=no IPV6_AUTOCONF=no DHCPV6=no dhclient-script overwrites /etc/resolv.conf whenever the interface comes up, which PEERDNS="no" should prevent. With NetworkManager.service it seems to work correctly (resolv.conf is not overwritten). > dhclient-script overwrites /etc/resolv.conf whenever the interface comes up,

That looks like a completely different issue, original report is about static ip addresses. Please file separate bug for dhcp component.
For the original issue, we probably need https://git.fedorahosted.org/cgit/initscripts.git/commit/?id=3d1f30095582f84206826f7ede970c45e5a6b5ba Is there a chance we'll see this included in a point release? c471fb25f02d2e595995e7c884bbdbfe3b19ef78 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
